e.g. rock debris, scree from the lower part of the hillside, swamp soil and
sediments from ancient lakes on the valley bottom. A preliminary estimate of
the volume of the slide is 10–20 million m3. The area
of the debris tongue is ca. 1,5 km2 and the debris is up to 20–30 m thick. The thickness is 5–10 m in many

a small amount of their heat to the atmosphere
when the currents form. The temperature of the current can vary from 100°C up
to 800°C. Depending on the density PDCs can be categorized into two groups. If
the column contains a lot of solid material while it collapses it is called
pyroclastic flows, however, if the quantity of solid material is low compared
to the gases it is called a pyroclastic

The situation was reviewed this morning by scientists from IMO, the University of Iceland and the Civil Protection System of the Icelandic police. Scientists are now on the way to Askja to evaluate the impact of the rockslide and any remaining hazards. Traffic in the area is restricted until further notice. The responsible

by effusive basaltic volcanism, the period 7000-3000 years ago was
characterized by infrequent but large explosive silicic eruptions at the
central volcano and effusive basaltic eruptions. In the last 3000 years a
mixture of both lava and tephra has been dominating.The

days. A volcanic crater has formed in the south-western corner of the cauldron. Erupted material from the vent continues to accumulate on the flanks of the crater. The rim of the volcanic crater is ~50 m lower than the surrounding ice cauldron. Volcanic spatter was observed from the vent, with ejected lava reaching heights of 100-200 m.
Unstable plumes of ash rise regularly from the vent.
